SPECIFICATION forming part of Letters Patent No. 623,889, dated April 25, 1899.

Application iiled November 29, 1897. Serial No. 660,021. (No model.)

To CLU tlf/wm, t may concern.:

Be it known that I, TIMOTHY G. DALY, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Advertising Apparatus, of which the following is a specification. i

This vinvention relates to an improvement in advertising devices; and it consists in the novel features of construction and relative arrangement of parts hereinafter fully described in the specication, clearly illustrated in the drawings, and particularly pointed out in the claims.

Reference is to be had to the accompanying three sheets of drawings, forming a part of this application, in which like reference characters are used to indicate like parts wherever they occur.

Figs. 9 and l0 represent views in elevation and section, showing parts of the advertisement-carrying device. Fig. ll represents a section on the line 1l ll of Fig. et. Figs. l2 and 13 represent detail views of parts of the mechanism shown in Figs. 5 and (i.

My present invention is designed as an iinproveinent on the advertising apparatus shown and described in Letters Patent of the United States No. 556,136, granted to me March 10, 1896. In the apparatus there shown certain devices were employed, including an intermittentlyoperated electric motor for moving an advertisement-carrying device, the said motor being operated by an indicator through the medium of electrical controlling devices. The present invention diifers from that referred to in the'employment of a continuously-operating motor mechanism and in dispensing with the electrical controlling devices, as well as in other respects.

In the right-hand portion of the casing d, as shown in Fig. l, is mounted an apparatus appropriate for the display of classified commercial advertisements or of railroad timetables arranged in the alphabetical order of the stations, the said apparatus being controlled by an indicator, and in the left-hand portion of the casin gis mounted an intermittently and automatically operating device appropriate for the display of general or unclassified advertisements. Power is furnished to both sections by a continuously-- running electric motor b, which operates a shaft b. An endless advertisement-carrying device or belt c is arranged to be driven by said motor, and suitable rolls c c are provided for the support and progression of said device. The device as here shown consists of two endless parallel sprocket-chains c2 c2, connected at intervals by rods c3, between which are supported advertising-cards c4. The cards are attached to the rods by means of connections c5, and since the cards are flexible they easily conform to the rolls c when passing around the same. The cards may be attached by rivets to the connector c5 or in any other suitable manner which will allow them to be readily changed. The casing a is provided-in front with openings, such as a', preferably covered with a glass a2, behind which the cards are displayed.

Referring for the present to the mechanism shown at the right in Fig. l and illustrated in detail in subsequent igures, c6 designates a large sprocket-wheel attached to the shaft of one of the lower rolls c', which constitutes the driving-roll for the advertisement-belt. This sprocket-wheel is geared by a chain d to a smaller sprocket-wheel c', affixed to a shaft e, on the other end of which is splined an endwise-movable friction-disk f. This disk forms one half of a clutch whose other half is formed by a gear f', loosely mounted on the shaft e and continuously rotated by a pinion b2 on the motor-shaft o.

g is a ratchet-wheel mounted on a stud g and having teeth g2, whose outer ends are ilattened, as shown in Fig. ll. On the arbor of the friction-disk f is mounted a sleeve f2,

IOO

which is pressed toward the ratchet r/ by a spring f3 and is provided with a detent f, engaging the teeth of the ratchet.

f5 is a bell-crank lever pivoted to a fixed sind and having one arm engaged with the sleeve f2, while the other arm carries a brake f, adapted to bear on the edge of the disk When the detent f on the sleeve f2 rests on the flat tened outer end of any one of the teeth y2 on the ratchet g, the frietion-diskf will be pressed up against the gearf' and will be rotated thereby; but when the ratchet is in such a position that the detent f4 rests between two of the ratchet-teeth the pressure of the disk j" against the gearf will be insufficient to rotate the former. The arbor of the gear g is connected by a universal joint 7L with a shaft h, at whose opposite end is another universal joint h2, connecting the shaft with a small gear arranged at the back of an indicator-dial j. The gear i is connected by intermediates /I' and 1F to a gear t3 on a shaft lf., at whose outer end is a knob 71:'. The in termediate t" also meshes with a gear t4, attached to a bushing or sleeve m, which surrounds the shaft 7.. and has at its outer end a pointer n1'.

7.12 is a ratchet-wheel affixed to the shaft 7a, and 7e3 is a spring roller-pawl engagingr said ratchet-wheel. \Vhen the knob ft' is turned in a right-hand direction, the pointer m/ moves around the dial j and the ratchetwheel f7 also turns about its stud. The number of teeth in said ratchet .r/ is preferably made equal to the number of divisions on the face of the dial j, and the gearing at the back of the dial, as here shown, is so arranged that it takes about four turns of the knob 7c' to move the pointer m a dist-ance of one division on the dial and to rotate the gear g a distance of one tooth. Then the pointer m stops at a point of division on the dial, the deteutf", Fig. ll, is always on the crest or flat portion of a tooth gzof the ratchetwheel g.

The dial j is provided with spaces or divisions in which may be arranged indexes of the different classes of business advertising on the belt c, or when this side of the apparatus is used to advertise the time-table of a railroad the letters of the alphabet would be placed on the dial, the letter A, for instance, corresponding to all of the stations ou the road which begin with that letter, and the cards on the belt c would be arranged in corresponding order, a certain card, for instance, bearing the schedules of trains for all stations beginning with the letter A.

On the arbor of the friction-disk j" isa pinion/7, which meshes with a gear n, on whose shaft is a worm n. The latter meshes with a gear o, loosely mounted on the stud g below the ratchet-wheel g. A downwardlyprojecting pin g3, Fig. et, is affixed to the ratchet g, and a similar pin o', projecting upwardly past the lower end of the pin g3 and adapted to travel in the same concentric path therewith, is affixed to the gear 0. The arrangement is such that when the detent f rests on the crest of a tooth g2 of the ratchetwheel g, thereby setting the disk f, shaft c, gear n, worm fn', and gear o in motion, the parts will continue to revolve until the pin o' strikes against the pin (/3. This will cause the ratchet gto turn sufficiently to move the detentf over the edge of the tooth g2, against which it has been bearing, into the space bctween that tooth and the next succeeding one. The clutch ff' is thereby released and the brake f6 applied, with the effect of stopping the shaft c and'the movement of the belt c. Since the position of the pin g3 is determined bythe position of the pointer mon the indicator-dial, it therefore follows that the distance moved over by said pointer in passing from one point of division on the dial to another determines the number ot' rotations which the shaft c will make after being started from a position of rest.

The belt-driving roll c and preferably also the other belt -rolls c are provided with sprocket-wheels,around which the belt-chains c2 pass, so that a given number of rotations of the shaft c, resulting in a given number of rotations of the large sprocket c, will produce a given amount of travel of the belt c. The belt is arranged to come to rest always with one of the cards c1 opposite the opening a' in the casing a, and the particular card which finally occupies that position after a movement of the belt depends upon the position of the pointer m. It is therefore apparent that when a person wishes to consult the schedule of trains for a certain station on the road it is only necessary to turn the knob 7a' until the pointer lnz. comes opposite the initial letter of that station and then wait until the card bearing that schedule appears behind the opening c.

The pointer and knob on the dial are prevented from being turned backward by the engagement of the detentf" with the ratchet g.

The left-hand section of the casingais devoted'to an apparatus for displaying miscellaneous or unclassified advertisements. The belt and belt-driving appliances in this part of the device are similar -to those hereinbefore described, but in place of the indicator a continuously-rotating part is substituted, which operates a clutch at regular intervals and effects intermittent engagement between the motor-shaft l1 and the belt-driving mechanism.

Referring to Figs. 5, (i, 12, and 13, b2 is a pinion on the shaft b', which meshes with a loose gear f, forming one half of a clutch. The other half of said clutch is formed by an endwise-movable friction-drum f, splined to a shaft whose opposite end carries a small sprocket-wheel engaging a drive-chain d.

f2 is a sleeve 011 the arbor of the disk f, held from rotation by an arm fs, which slides between stationary guide-pins f, and f l is a detent on the end of said sleeve.

IOO

IIO

p is a gear, which is constantly rotated by means of a worm fr, bevel-gears r' r2, a gear r3, and a pinion b3 on the motor-shaft b. the face of the gear p, near its edge, is a eamboss p, which has a vertical face parallel to the face of the gear. Once in every rotation of the gear p the boss 29 comes in contact with the detent f4 and throws the friction-disk f into engagement with the gear f. This engagement is continued as long as the detent rests upon the boss, and while it continues the advertisement-carrying belt is moved through a predetermined distance, sufficient to bring a fresh advertisement-card into view through an opening in the front of the casing similar to the opening a. The clutch is then automatically released as the boss passes out of engagement with the detent, and after a period of rest, the length of which depends upon the speed of the gear p, the belt is again moved to bring a fresh card into view by the rengagementof the detent f4 and the bossp.

During the periods of rest of the frictiondrum fit and the shaft to which itis splined are lockedV by a mechanism lconstructed as follows: A wormf10 is formed on the hub of the friction-disk, which meshes with agears, loosely mounted on a vertical stud. Below said gear s is a sleeve t, which is vertically movable on said stud, butis held from rotation thereon. The gear sis provided with an aperture which is adapted to receive a pin t on the sleeve t. A spring lf2 exerts an upward pressure on the sleeve. t3 is an arm affixed to the sleeve t and provided at its lower end with a hook which is adapted to be engaged by a second cam-boss p2 on the gear p. The arrangement is such that just before the detent f4 becomes engaged by the boss p the hooked arm t3 becomes engaged by the boss p2 and the sleeve t is drawn downwardly, thereby drawing the pin t out of the aperture in the gear s and permitting the friction-disk f to be rotated. Just after the boss p' passes off from the detent f4 the boss p2 releases the hooked arm i3, and since by this time the gear s has completed a rotation the pin t again enters the aperture in said gear and locks the friction-disk and its shaft.

I do not wish to limit myself to the precise construction and arrangement of the parts shown, since many modifications may be made without departing from the spirit of my invention.

Having thus explained the nature of my invention and described a way of constructing and using the same, although without having attempted to set forth all the forms in which it maybe embodied or all the modes of its use, I declare that what I claim isl. In an advertising apparatus, an advertisement-carrying device, a norm ally-inactive mechanism for driving the same, a continuously-run ning motor, an indicator, and means whereby different positions of the indicator establish operative connection for different On i lengths of time between the motor and the driving mechanism.

2. In an advertising apparatus, a continuously-operating-motor mechanism, an advertisement-carrying device arranged to be driven by said motor mechanism, a clutch adapted to effect engagement between the advertisement-carrying device and the motor mechanism, an indicator adapted to operate the clutch, and devices arranged between the indicator and clutch, whereby the duration of engagement between the advertisementcarrying devices and the motor mechanism is made to depend upon the position of the indicator.

3. In an advertising apparatus, an advertisement-carrying device comprising a pair of endless parallel-moving sprocket-chains, rods connecting these chains atintervals, and flexible advertising-cards attached at both ends to said rods.

4. In an advertising apparatus, a displaybelt comprising two parallel sprocket-chains, a series of rods connecting said chains at intervals, a series of flexible advertising-cards, and fastening devices securing the cards at both ends to the rods and constructed to permit the removal of said cards without disconnecting the chains and rods.

5. In an advertising apparatus, an advertisement-carrying device, a clutch having a normally-inactive part connected with said device, andacontinuously-driven part adapted to become engaged with thev normally-inactive part so as to move the advertisementcarrying device,an indicator having an index, a wheel having clutch-operating projections corresponding to the divisions of the indicator and adapted to effect engagement between the parts of the clutch when said indicator is moved, and a trip mechanism adapted to automatically release the clutch after a predetermined movement of the advertisement-carrying device.

6. In an advertising apparatus, a clutch comprising a continuously-driven part, a normally-inactive and longitudinally-movable friction-disk, a detent, a spring arranged between the latter and the friction-disk, a wheel having teeth which engage the detent, the disk and the continuously-driven part being engaged and the former rotated when the detent rests on the crest of one`of said teeth, and disengaged when said detent rests between two of said teeth, and a trip mechanism operated 'by the disk and adapted to automatically move the toothed wheel from the first said relation with respect to the detent, to the second said relation, after a predetermined movement of the disk.

7. An advertising apparatus comprising a casing, two endless advertising-belts mounted therein, a single continuously-operating motor mechanism, automatic means for intermittently coupling said motor mechanism to one of the belts, whereby an automatic IOO IIO

sion to the latter, and mechanism interposed I5 between the indicator, the bolt, and the motor, whereby different positions of the indicator produce different amounts of travel in the belt.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 23d day of November, A. D. 1897.
